Passive Infra-red Transducer (25m range)
  > Robust Construction
  > Operating temperature -30°C to +60°C
  > Easily interfaced to any Alarm system
  > Low nuisance Alarm rate
  > IP 65

The Passive Infra-Red transducers are based upon a highly reliable Lithium tantalate pyroelectric detector, which combines very low noies with a high signal to noise ratio. The transducers employ very robust construction techniques and can therefore be confidently deployed in the most adverse environments. Both single and dual element variants are available, the latter possesses the ability to indicate direction of intrusion. A wide range of output levels permit the devices to be easily integrated into the majority of existing alarm systems. The Passive Infra-Red transducers is intended for use in military, paramilitary, security services and border type applications.
